What is the least number that has 4 factors that are all the sme? each factor is greater then 1, and can have 1 and itself as factors.

Hello

the factors can't be 1.the factors have to be odd.they have to be the same.offhand i would say 3*3*3*3 would be equal to 9*9 = 81.the number 81 has 4 odd factors that are all the same.can't be 1 because 1 doesn't counts as a factor.a prime number has 2 factors.1 and itself.every number has a factor of 1 and itself.
have  a nice day
